“…α-Al 2 O 3 is a high-temperature stable form of Al 2 O 3 , which is one of the important structural materials because of its low cost, low thermal conductivity, high hardness, high flexure strength, high dielectric strength, excellent chemical inertness, high wear resistance, and corrosion resistance. [1][2][3] These excellent properties make Al 2 O 3 coating have a high potential for broad applications in wear, corrosion, and dielectric protections. Atmospheric plasma spraying (APS) processes are performed at atmospheric pressure with high input power and plasma flame temperatures.…”

In this study, plasma sprayed Al2O3‐Cr2O3 coatings with different contents of graphene nanosheets were prepared for investigating effects of the graphene on microstructure, mechanical properties and wear behavior of the coating. The experimental results showed that graphene increased the porosity and the micro‐hardness of the coating. But excessive graphene decreased the micro‐hardness remarkably. Besides, the anti‐crack initiation and propagation abilities of the coatings with graphene improved significantly. The wear rate of the coatings decreased firstly and then increased with increasing the graphene content. Impressively, the wear rates of the coating with 2.9% graphene decreased by 33.5% and 36.7%, compared with those of the coating without graphene under normal loads of 5N and 15N, respectively. The main wear mechanisms of the coatings with and without graphene are brittle fracture and abrasive wear.This article is protected by copyright. All rights reserved

“…Graphene/aluminum composites have high strength, high conductivity and high toughness. Thus, graphene/aluminum composites have wide application potentiality in the electronics, automotive and aerospace industry [1,2,3,4,5,6,7,8]. However, graphene/aluminum composites are difficult to prepare; because of the poor wettability between Al and graphene, the graphene aggregates easily in the Al matrix, which can decrease the mechanical properties of the composites [9,10].…”

This research explored a novel chemical reduction of organic aluminum for plating Al on a graphene surface. The thermodynamics of the Al plating reaction process were studied. The Al plating process consisted of two stages: the first was to prepare (C2H5)3Al. In this reaction, the ΔH(enthalpy) was 10.64 kcal/mol, the ΔG(Gibbs free energy) was 19.87 kcal/mol and the ΔS(entropy) was 30.9 cal/(mol·K); this was an endothermic reaction. In the second stage, the (C2H5)3Al decomposed into Al atoms, which were gradually deposited on the surface of the graphene and the Al plating formed. At 298.15 K, the ΔH was −20.21 kcal/mol, the ΔG was −54.822 kcal/mol, the ΔS was 116.08 cal/(mol·K) and the enthalpy change was negative, thus indicating an endothermic reaction.
